DOWNLOAD EBOOKThe rotorcraft industry is developing a number of techniques, methodologies, and associated equipment for monitoring health and usage of critical rotorcraft flight components. Industry is planning to incorporate this technology on a number of new aircraft. The Federal Aviation Administration (FAA) has the responsibility for certification of these aircraft and the equipment they contain. This effort is concerned with the health and usage equipment. To best accomplish the certification of these equipment, the FAA expects to develop detailed certification criteria addressing specific issues of concern. In the near-term, the FAA objective is to develop a better understanding of what is being developed by industry (with emphasis on United States industry), what firms are involved, who are the key people involved, what parts of this technology are mature to the point that some airworthiness credit may be appropriate, and what parts of this technology are not yet mature. With information such as this, the issues that need to be address via certification criteria can be determined quickly. This effort is principally intended to provide support in reaching the FAA's near-term objectives. This report describes the results of an extensive literature search of health and usage monitoring technology. Over 1,000 abstracts were reviewed and analyzed. The report contains a description of 20 systems and abstract of 90 papers pertinent to health and usage monitoring.

DOWNLOAD EBOOKAsset Management strategies are converting from a reflective/reactive maintenance to preventive and predictive maintenance methods. With the increasing need for higher safety standards and to reduced operational and maintenance costs, the need for methods to diagnose and predict the occurrence of failure is becoming an imminent requirement. With the application of present day technology and non-destructive evaluation and monitoring techniques, this report proposes a framework based on which active diagnosis of the condition of a unit (vehicle/structure) can be monitored towards providing better maintenance practices. In the world of Rotorcrafts Heath and Usage Monitoring Systems (HUMS) have started to catch traction due to the higher safety standards it provides by continuous awareness of internal working and the reduced maintenance and replacement costs assured by this system. A well developed comprehensive system designed for a specific aircraft platform would be able to analyze critical failure modes, analyze usage and conditional data of the entire structure (extrinsic and intrinsic) and provide a prognostic knowledge to the user/operator and owner of the units. Within approved safety margins and threshold levels, a HUMS system can provide cost saving by alerting the maintenance crew when the optimal time to change parts are, avoiding underusing or overusing a component, and also to unexpected failures. This thesis attempts to provide a framework of analysis methodologies and logic flow for a user, engineer, designer or operator to establish a comprehensive HUMS system on a unit so as to ensure the full utilization of present technology. Here Usage-Based Monitoring (UBM) data and Condition-Based Monitoring (CBM) data are collected through sensor networks placed strategically through a Functional Hazard Assessment (FHA) regiment in order to provide the end user and maintenance staff accurate and immediate information on the diagnostics and prognostics of the unit. This allows for better maintenance scheduling, lower labor costs, lower inventory costs and above all safety. Soon an established HUMS system will be mandatory on most large scale-expensive commercial products such as aircrafts, ships, bridges, etc. so as to ensure the safety of its users and in the long run allow the owners to benefit from the inevitable financial savings that it promises.

DOWNLOAD EBOOKIntegrated Vehicle Health Management: Implementation and Lessons Learned is the fourth title in the IVHM series published by SAE International. This new book introduces a variety of case studies, lessons learned, and insights on what it really means to develop, implement, or manage an integrated system of systems. Integrated Vehicle Health Management: Implementation and Lessons Learned brings to the reader a wide set of hands-on stories, made possible by the contribution of twenty-three authors, who agreed to share their experience and wisdom on how new technologies are developed and put to work. This effort was again coordinated by Dr. Ian K. Jennions, Director of the IVHM Centre at Cranfield University (UK), and editor of the previous books in the series. Integrated Vehicle Health Management: Implementation and Lessons Learned, with seventeen, fully illustrated chapters, covers diverse areas of expertise such as the impact of trust, human factors, and evidential integrity in system development. They are complemented by valuable insights on implementing APU health management, aircraft health trend monitoring, and the historical perspective of how rotorcraft HUMS (Health and Usage Monitoring Systems) opened doors for the adoption of this cutting-edge technology by the global commercial aviation industry.

DOWNLOAD EBOOKThis document collates the ways and means that existing sensors can identify the platform's exposure to volcanic ash. The capabilities include real-time detection and estimation, and post flight determinations of exposure and intensity. The document includes results of initiatives with the Federal Aviation Administration (FAA), the European Aviation Safety Agency (EASA), the International Civil Aviation Organization (ICAO), Transport Canada, various research organizations, Industry and other subject matter experts. The document illustrates the ways that an aircraft can use existing sensors to act as health monitoring tools so as to assess the operational and maintenance effects related to volcanic ash incidents and possibly help determine what remedial action to take after encountering a volcanic ash (VA) event. Finally, the document provides insight into emerging technologies and capabilities that have been specifically pursued to detect volcanic ash encounters but are not yet a part of an airplane's standard fit. The constituents, concentration, and size of volcanic ash particles are highly variable. Volcanic ash can also damage or degrade aircraft sub-systems. In the past 30 years, more than 90 jet-powered commercial airplanes have encountered clouds of volcanic ash and suffered damage as a result. The increased availability of satellites and the technology to transform satellite data into useful information for operators have reduced the number of volcanic ash encounters, but the damage that these encounters can inflict on aircraft sub-systems is also highly variable and has the potential to be catastrophic. Understanding how sensors on an airborne platform could help determine that an aircraft is in a volcanic ash environment or has recently flown through volcanic ash is thus of considerable value.

DOWNLOAD EBOOKThis open access book presents established methods of structural health monitoring (SHM) and discusses their technological merit in the current aerospace environment. While the aerospace industry aims for weight reduction to improve fuel efficiency, reduce environmental impact, and to decrease maintenance time and operating costs, aircraft structures are often designed and built heavier than required in order to accommodate unpredictable failure. A way to overcome this approach is the use of SHM systems to detect the presence of defects. This book covers all major contemporary aerospace-relevant SHM methods, from the basics of each method to the various defect types that SHM is required to detect to discussion of signal processing developments alongside considerations of aerospace safety requirements. It will be of interest to professionals in industry and academic researchers alike, as well as engineering students. This article/publication is based upon work from COST Action CA18203 (ODIN - http://odin-cost.com/), supported by COST (European Cooperation in Science and Technology). COST (European Cooperation in Science and Technology) is a funding agency for research and innovation networks. Our Actions help connect research initiatives across Europe and enable scientists to grow their ideas by sharing them with their peers. This boosts their research, career and innovation.
